Without a license, NL5 operates as a Demo version. The Demo version has all full-function features available, with a limited total number of components in the schematic. Although the Demo version does not allow entering components above the limit, it still can read and simulate schematics with unlimited number of components, provided as an NL5 demonstration, or created with a special type of a license.

To use NL5 as a Demo version, simply download NL5, and start using it right away.

While the Demo version is quite suitable for students and amateurs, professionals might consider obtaining one of the full-function licenses.
